title: [Intracranial lageniform aneurysms: imaging features, diagnosis and treatment strategies].
abstract: OBJECTIVE
  To explore the imaging features, diagnosis and treatment strategies of intracranial lageniform aneurysms.
  
  
  METHODS
  The clinical characteristics and therapeutic outcomes of 6 patients with intracranial lageniform aneurysms were retrospectively analyzed.
  
  
  RESULTS
  All the 6 aneurysms, including 5 anterior communicating artery aneurysms and 1 middle cerebral artery (MCA) aneurysm, were diagnosed by CT, DSA and (or) MRA. Pretreatment CT revealed subarachnoid hemorrhage and intracranial hematoma surrounding the ruptured aneurysm. Three dimensional DSA showed that all the lageniform aneurysms contained two parts, the larger false aneurysm and the smaller true aneurysms. All the 5 Acom aneurysms were coiled and the MCA aneurysm was clipped. Two patients with coiling developed serious brain edema, and acute decompressive craniectomy was performed to 1 of them. Pathological examination of the surgical specimens confirmed that pseudoaneurysm formed the larger part of the lageniform aneurysm. One patient died of brain hernia, and the other 5 patients were discharged with good GOS. All the patients showed stable neurological status during the 3-month follow-up.
  
  
  CONCLUSIONS
  Lageniform aneurysm is a complex aneurysm consisting in larger part of false aneurysm and in smaller part of true aneurysm, and early intervention with individualized surgeries is recommended.
